1. A server, comprising:
an enclosure including a housing and an interior space within the housing, wherein the interior space defines a plurality of sockets;
a backplane secured to the housing within the interior space adjacent a rear portion of the plurality of sockets, wherein the backplane includes at least one backplane connector adjacent the rear portion of each socket of the plurality of sockets; and
a computing module receivable in a first socket of the plurality of sockets, wherein the computing module includes:
a chassis that is slidable within the first socket along a first axis;
a printed circuit board (PCB) that is slidable relative to the chassis along a second axis that is collinear with or parallel to the first axis; and
at least one PCB connector attached to the PCB for mating with the backplane connector of the first socket when the computing module is received in the first socket, wherein the at least one PCB connector is a plurality of PCB connectors electrically attached to the PCB, and
wherein the computing module further includes:
a stiffening plate interconnecting the plurality of PCB connectors; and
a plurality of stiffening members interconnecting the stiffening plate to the PCB,
wherein the stiffening plate and the plurality of stiffening members are configured resist bending moments induced in the plurality of PCB connectors as the computing module is inserted into the first socket of the enclosure; and
a biasing apparatus interconnected between the chassis and the PCB that is configured to allow the PCB to slide along the second axis when the chassis is inserted into the first socket along the first axis.
 
6. A server, comprising:
an enclosure including a housing and an interior space within the housing, wherein the interior space defines a plurality of sockets;
a backplane secured to the housing within the interior space adjacent a rear portion of the plurality of sockets, wherein the backplane includes at least one backplane connector adjacent the rear portion of each socket of the plurality of sockets; and
a computing module receivable in a first socket of the plurality of sockets, wherein the computing module includes:
a chassis that is slidable within the first socket along a first axis;
a printed circuit board (PCB) that is slidable relative to the chassis along a second axis that is collinear with or parallel to the first axis;
at least one PCB connector attached to the PCB for electrical connection with the at least one backplane connector of the first socket; and
a biasing apparatus interconnected between the chassis and the PCB that is configured to allow the PCB to slide along the second axis when the chassis is inserted into the first socket along the first axis.
 
12. A server, comprising:
an enclosure including a housing and an interior space within the housing, wherein the interior space defines a plurality of sockets;
a backplane secured to the housing within the interior space adjacent a rear portion of the plurality of sockets, wherein the backplane includes at least one backplane connector adjacent the rear portion of each socket of the plurality of sockets; and
a computing module receivable in a first socket of the plurality of sockets, wherein the computing module includes:
a chassis that is slidable within the first socket along a first axis;
a printed circuit board (PCB) that is slidable relative to the chassis along a second axis that is collinear with or parallel to the first axis;
at least one PCB connector attached to the PCB for electrical connection with the at least one backplane connector of the first socket;
a frame that is slidably attached to the chassis for movement along the second axis, wherein the PCB is rigidly attached to the frame for movement therewith along the second axis; and
a biasing apparatus interconnected between the chassis and the PCB that is configured to allow the PCB to slide along the second axis when the chassis is inserted into the first socket along the first axis.
